Injector Help

how easy is it to remove fuel injector out of the rav so i can get them cleaned. also am i supposed to have 2 sets of 2 different colours

There is quite a lot of digging to do. The injectors are held in by the fuel rail so the valve cover, air flow meter and EGR valves need to come off. Once the fuel rail is off the injectors just twist out of the housings.

I can't answer your question about the colours. I presume you have 2 different colours which is making you suspicious that some have been changed. Toyota often pair up coils and plugs so it wouldn't surprise me if the injectors were paired - probably 1&4 and 2&3.

Incidentally I would try a bottle of injector cleaner if you think you have injector problems. I think Wynns do one and it really is quite good if you have an injector sticking.
